O-ring 18x6 NBR 70 ShA Nitrile Rubber Seal 100 pcs

O-ring 18x6 NBR 70 ShA is a technical sealing ring manufactured from nitrile rubber designed for reliable sealing in hydraulic systems, pneumatic installations and industrial machinery. With an inner diameter of 18 mm and a cross section of 6 mm, this O-ring provides stable sealing performance in mechanical assemblies exposed to oils, lubricants and industrial fluids. The product is supplied in packs of 100 pieces, making it a practical solution for maintenance departments, repair workshops and industrial production environments.

NBR nitrile O-rings are among the most widely used sealing components in industrial engineering. Their resistance to mineral oils, greases and many petroleum based fluids makes them suitable for a broad range of hydraulic and mechanical systems. The hardness rating of 70 ShA provides a balanced combination of elasticity and mechanical durability.

Construction and design

The O-ring 18x6 NBR 70 ShA has a circular cross section that allows uniform compression between sealing surfaces. This geometry ensures effective sealing and prevents leakage of fluids or gases in both static and dynamic mechanical systems.

NBR nitrile rubber offers excellent flexibility combined with resistance to mechanical wear. These properties allow the sealing ring to maintain stable performance in oil lubricated environments and under continuous industrial operation.

A hardness level of 70 Shore A is one of the most commonly used standards in industrial sealing technology.
